2011 monaco diplomat 43dft ignition time

[Toddoo]

I am the owner of a 2011 Monaco diplomat 43dft for the last 9 months. I have noticed on a recent trip from Oklahoma to Georgia that when I turned the key to run position and wait for the computer screen to complete its 10 second start up, upon turning to the crank position the coach is dead with no cranking on the starter. The dash does not display any warning or wait before cranking as far as something warming up prior to ignition. I just wanted to hear from fellow owners if I am missing something. I did check the batteries and they tested good. thanks

the time varies from start to start how long you have to wait

sorry, yeah if you wait for 30 secs's ish it will turn over, and it has a 425 cummins isl

Ignition switch itself?....Starter Solenoid/Starter Assembly....connections to starter itself and even connections at the batteries...what happens when this exhibits the symptoms...do you do the whole sequence again and it starts?..or do you force the key and hold it hard to the stop to start?...need a bit more info..and is it a cummins or a maxxforce engine?
